在 VS Code 中调试
本指南将引导您完成设置 VS Code 以调试您的 Tauri 应用的核心进程。
安装 vscode-lldb
扩展。
创建一个 .vscode/launch.json
文件,并将以下 JSON 内容粘贴到其中
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "type": "lldb", "request": "launch", "name": "Tauri Development Debug", "cargo": { "args": [ "build", "--manifest-path=./src-tauri/Cargo.toml", "--no-default-features" ] }, // task for the `beforeDevCommand` if used, must be configured in `.vscode/tasks.json` "preLaunchTask": "ui:dev" }, { "type": "lldb", "request": "launch", "name": "Tauri Production Debug", "cargo": { "args": ["build", "--release", "--manifest-path=./src-tauri/Cargo.toml"] }, // task for the `beforeBuildCommand` if used, must be configured in `.vscode/tasks.json` "preLaunchTask": "ui:build" } ]}
这直接使用 cargo
构建 Rust 应用程序,并在开发和生产模式下加载它。
请注意,它不使用 Tauri CLI,因此不会执行独有的 CLI 功能。beforeDevCommand
和 beforeBuildCommand
脚本必须预先执行,或者在 preLaunchTask
字段中配置为任务。下面是一个 .vscode/tasks.json
文件的示例,它包含两个任务:一个用于启动开发服务器的 beforeDevCommand
,一个用于 beforeBuildCommand
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "ui:dev", "type": "shell", // `dev` keeps running in the background // ideally you should also configure a `problemMatcher` // see https://vscode.js.cn/docs/editor/tasks#_can-a-background-task-be-used-as-a-prelaunchtask-in-launchjson "isBackground": true, // change this to your `beforeDevCommand`: "command": "yarn", "args": ["dev"] }, { "label": "ui:build", "type": "shell", // change this to your `beforeBuildCommand`: "command": "yarn", "args": ["build"] } ]}
现在你可以在 src-tauri/src/main.rs
或任何其他 Rust 文件中设置断点,然后按 F5
开始调试。
Visual Studio Windows Debugger 是一个仅限 Windows 的调试器,通常比 vscode-lldb
更快,并且对某些 Rust 功能(如枚举)有更好的支持。
安装 C/C++ 扩展,并按照 https://vscode.js.cn/docs/cpp/config-msvc#_prerequisites 的说明安装 Visual Studio Windows Debugger。
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "Launch App Debug", "type": "cppvsdbg", "request": "launch", // change the exe name to your actual exe name // (to debug release builds, change `target/debug` to `release/debug`) "program": "${workspaceRoot}/src-tauri/target/debug/your-app-name-here.exe", "cwd": "${workspaceRoot}", "preLaunchTask": "ui:dev" } ]}
请注意,它不使用 Tauri CLI,因此不会执行独有的 CLI 功能。tasks.json
与 lldb
相同,不同之处在于您需要添加一个配置组,并将 launch.json
中的 preLaunchTask
指向它,如果您希望它在启动前始终进行编译。
这里有一个运行开发服务器(相当于 beforeDevCommand
)和编译 (cargo build
) 的示例,作为一个组,要使用它,请将 launch.json
中的 preLaunchTask
配置更改为 dev
(或您给您的组命名的任何名称)。
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "build:debug", "type": "cargo", "command": "build", "options": { "cwd": "${workspaceRoot}/src-tauri" } }, { "label": "ui:dev", "type": "shell", // `dev` keeps running in the background // ideally you should also configure a `problemMatcher` // see https://vscode.js.cn/docs/editor/tasks#_can-a-background-task-be-used-as-a-prelaunchtask-in-launchjson "isBackground": true, // change this to your `beforeDevCommand`: "command": "yarn", "args": ["dev"] }, { "label": "dev", "dependsOn": ["build:debug", "ui:dev"], "group": { "kind": "build" } } ]}
